2. To determine wavelength of Sodium light by Fresnel’s Biprism.
3. To determine dispersive power of a prism using Mercury light.
4. Using Newton’s rings find out the wavelength of the given monochromatic source.
5. Using Michelsons’s interferometer, find out l and Dl for Sodium Light.
6. To determine Brewster’s angle and refractive index of glass by using spectrometer and Polaroids.
7. To study damping of a compound pendulum and to determine the quality factor.
8. To study the charging of a condenser by unidirectional varying voltage pulses/alternating voltage pulses and then to integrate them.
9. Study of dependence of velocity of wave propagation on line parameter using torsional wave apparatus.
10. To study the variation of magnetic field along the axis of a current carrying circular coil. Plot the necessary graph and hence determine the radius of circular coil.
